--- Comment #31 from Takashi Iwai
I had already tried to do a test without load the driver, and the dmesg.txt file is created, but when I copy it manually somewhere in the filesystem, it appears in the position that I have chosen, but after rebooting the system, is no more, no original and no copy.
Where did you copy? The crash dump kernel boots in its own ramdisk, so its root fs will be gone after reboot. Usually kdump mounts the local fs in /kdump/mnt/*, so you can copy there, too. Also you can copy to a usb-disk or remote ssh copy, IIRC. The likely reason you didn't get any dumps is the lack of free space. As default, openSUSE assigns fairly small amount of root partition, and the dump doesn't fit in /var/crash. You can change it to another partition, e.g. /home/crash, via yast2 kdump, then reboot and retest. -- You are receiving this mail because: You are on the CC list for the bug.
